Abstract
The utility model relates to the technical field of compressors, in particular to a shaded pole motor compressor kirsite end cover which comprises an end cover body integrally formed by engineering plastics. Hole sites are formed in two sides of the end cover body. Kirsite locating sleeves are fixedly arranged in the hole sites. A bearing inner hole is formed in the middle of the end cover body. A bearing used for being connected with a shaded pole motor is fixedly arranged in the bearing inner hole. The shaded pole motor compressor kirsite end cover is low in material cost and easy to process. In addition, the bearing is fixedly arranged in the end cover body in advance so that matching of the bearing and the end cover is tight matching and free from looseness. When the bearing receives radial force in the process of working, the end cover body can buffer the radial force received by the bearing relying on the elastic character of the engineering plastics, and therefore tightness of the bearing and the end cover is ensured.
Description
Technical field
The utility model relates to the Compressor Technology field, relates in particular to a kind of motor with cup rotor compressor zinc alloy end cap.
Background technique
In compressor, usually need to use the zinc alloy end cap that bearing and motor with cup rotor (being shaded pole motor) are rotationally connected.At present, traditional motor with cup rotor compressor zinc alloy end cap on market, as depicted in figs. 1 and 2, zinc alloy end cap 100 is usually one-body molded by zinc alloy, the both sides of zinc alloy end cap 100 offer positioning hole 101, and the centre of zinc alloy end cap 100 offers the brearing bore 103 for running in bearings 102.
The shortcoming of above-mentioned motor with cup rotor compressor zinc alloy end cap is: 1, all one-body molded by zinc alloy, the materials cost is high; 2, the assembling of zinc alloy end cap and bearing needs interference fit, makes the requirement on machining accuracy of brearing bore higher, and needs special-purpose bearing assemble press equipment to assemble; 3, after running in bearings, if bearing with coordinating of brearing bore occur the gap or excessively coordinate, make bearing be subject to radial force for a long time at work and cause the matching gap between bearing and end cap to increase gradually, and then causing the machine operation noise to increase, even cause the zinc alloy end cap damage or scrap; 4, the hardness due to zinc alloy is high, causes the processing cost of zinc alloy end cap high.
The model utility content
The purpose of this utility model be to provide for the deficiencies in the prior art a kind of materials cost low, processing simple motor with cup rotor compressor zinc alloy end cap.
To achieve these goals, the utility model provides a kind of motor with cup rotor compressor zinc alloy end cap, comprise by the integrated end cap main body of engineering plastics, porose position is offered in the both sides of described end cap main body, described hole is fixedly installed the zinc alloy setting sleeve in the position, the centre of described end cap main body offers brearing bore, is fixedly installed in described brearing bore to be useful on the bearing that connects motor with cup rotor.
Preferably, described zinc alloy setting sleeve is for being embedded in position, described hole.
Preferably, described bearing is for being embedded in described brearing bore.
Preferably, described bearing is rolling bearing.
The utility model beneficial effect is:
1, engineering plastics is one-body molded to be manufactured in order to adopt due to end cap main body of the present utility model, and the price of engineering plastics is simple lower than zinc alloy and engineering plastics processing, so materials cost of the present utility model is low, processing simple;
2, due to zinc alloy setting sleeve of the present utility model for being fixedly installed in advance the end cap main body, increased like this end cap to the lock fastening force, can not cause end cap loosening because of vibrations and the heating that machine operation produces;
3, due to bearing of the present utility model for being fixedly installed in advance the end cap main body, so bearing is drive fit with coordinating of end cap, not loosening, when being subject to radial force at work, the flexible characteristic of material of end cap main body dependence self engineering plastics, the radial force that bearing is subject to cushions, thereby guarantees the tightness of bearing and end cap;
4, the positional accuracy of end cap main body of the present utility model is to rely on plastic mould to guarantee, so the precision conformity of end cap is better.
Description of drawings
Fig. 1 is traditional motor with cup rotor compressor zinc alloy end cap and the structural representation of bearing.
Fig. 2 is traditional motor with cup rotor compressor zinc alloy end cap and the generalized section of bearing.
Fig. 3 is decomposing schematic representation of the present utility model.
Fig. 4 is generalized section of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
please refer to Fig. 3 and Fig. 4, motor with cup rotor compressor zinc alloy end cap of the present utility model, comprise by engineering plastics (engineering plastics, refer to the mechanical-physical effect that to bear some strength, impact resistance is better, the macromolecular material of outstanding performance is being arranged aspect the complex environments such as heatproof, such as PC, PA, POM, Deng) integrated end cap main body 1, porose position 2 is offered in the both sides of end cap main body 1, be fixedly installed zinc alloy setting sleeve 3 in position, hole 2, the centre of end cap main body 1 offers brearing bore, be fixedly installed in brearing bore and be useful on the bearing 4 that connects motor with cup rotor.
Specifically, in position, hole 2, bearing 4 is for being embedded in brearing bore for pre-buried (being pre-plugged) for zinc alloy setting sleeve 3, and bearing 4 is rolling bearing.
In sum, materials cost of the present utility model is low, processing is simple; The utility model still adopts zinc alloy setting sleeve 3 to be positioning link, thus increased end cap to the lock fastening force, can not cause end cap loosening because of vibrations and the heating that machine operation produces; Bearing 4 of the present utility model is that pre-plugged is in end cap main body 1, so bearing 4 is drive fit with coordinating of end cap, not loosening, when being subject to radial force at work, the flexible characteristic of material of end cap main body 1 dependence self engineering plastics, the radial force that bearing 4 is subject to cushions, thereby guarantees the tightness of bearing 4 and end cap; The positional accuracy of end cap main body 1 of the present utility model is to rely on plastic mould to guarantee, so the precision conformity of end cap is better.
Should be noted that at last; above embodiment is only in order to illustrate the technical solution of the utility model; but not to the restriction of the utility model protection domain; although with reference to preferred embodiment, the utility model has been done to explain; those of ordinary skill in the art is to be understood that; the technical solution of the utility model is modified or is equal to replacement, all belong to protection domain of the present utility model.
